The International Conference on Condensed Matter Nuclear Science is held annually on a different continent every time. This volume documents the proceedings of the 11th conference held in Marseilles, France. It includes articles that indicate the current position of the condensed matter nuclear science field. With an extensive collection of articles, this volume is indispensable since very few papers related to this field are published in scientific journals. Contents: Reproducibility, Controllability and Optimization of LENR Experiments (D J Nagel); Superwave Reality (I Dardik); Generation of Heat and Products During Plasma Electrolysis (T Mizuno et al.); Electron Screening Constraints for the Cold Fusion (K Czerski et al.); Low Mass 1.6 MHz Sonofusion Reactor (R Stringham); Evidence of Microscopic Ball Lightning in Cold Fusion Experiments (E H Lewis); Co-Deposition of Palladium with Hydrogen Isotopes (J Dash & A Ambadkar); Possible Nuclear Transmutation of Nitrogen in the Earth''s Atmosphere (M Fukuhara); Theoretical Model of the Probability of Fusion Between Deuterons within Deformed Lattices with Microcracks at Room Temperature (F Fulvio); Effective Interaction Potential in the Deuterium Plasma and Multiple Resonance Scattering (T Toimela); Theoretical Study of Nuclear Reactions Induced by Bose-Einstein Condensation in Pd (K-I Tsuchiya & H Okumura); Phonon-Exchange Models: Some New Results (P L Hagelstein); Cold Fusion Phenomenon and Solid State Nuclear Physics (H Kozima); Effects of Atomic Electrons on Nuclear Stability and Radioactive Decay (D V Filippov et al.); Recent Cold Fusion Claims: Are They Valid (L Kowalski); and other papers. Readership: Academics and researchers in nuclear physics.
